GAP : An area having permanent protection from conversion of natural land cover and a mandated management plan in operation to maintain a primarily natural state, but which may receive use or management practices that degrade the quality of existing natural communities. GAP : An area having permanent protection from conversion of natural land cover for the majority of the area, but subject to extractive uses of either a broad, low-intensity type or localized intense type. It also confers protection to federally listed endangered and threatened species throughout the area. GAP : Lack of irrevocable easement or mandate to prevent conversion of natural habitat types to anthropogenic habitat types. Allows for intensive use throughout the tract. Also includes those tracts for which the existence of such restrictions or sufficient information to establish a higher status is unknown. Page 2 of 5

3 PREDICTED HABITAT MODEL(S): Year-round Model: Habitat Description: Customized Model: The leatherback is primarily a tropical nester but is known to wander more widely than other sea turtles. They are mainly pelagic, seldom approaching land except for nesting (Eckert 1992; Martof et al. 198), but it occasionally enters shallow bays and estuaries. Invertebrates are the main dietary staple, especially jellyfish, which are eaten at or near the surface of the water. The turtles sleep while floating on the surface (Ernst et al. 199). In the summer, they concentrate in waters mostly 2- m deep near Cape Canaveral, Florida. They nest on sloping sandy beaches free of abrasive rocks and coral, backed up by vegetation, often near deep water and rough seas. They are primarily tropical beach nesters. The largest colonies use continental, rather than insular, beaches (CSTC 199). This species may rapidly occupy newly formed nesting habitat (Pritchard 1992). The absence of a fringing reef and with obstruction free approaches appears to be important [due to heavy body with soft skin] (Mortimer 1981). Nests are dug in sand at night in March-August and many are lost due to high tides. They lay up to 1+ clutches of 7-9 normal eggs at intervals of about 1-2 weeks. Most individuals nest every 2-3 years. Eggs hatch in 8-1 weeks. After nesting, leatherbacks follow schools of jellyfish to temperate waters and then return to the tropics (Ernst et al. 199). Stacy Smith, 7June5 Brackish/Salt water type was selected for this species, but since water is selected as a map unit, this should serve to limit this species' model to Brackish/Salt water habitats. I therefore unselected water type from the drop-down menu above. MJR 29aug7. Added FW and SW 12m and 9999 (unlimited) FROM and INTO buffers respectively. MJR 3 January 28. This species is highly pelagic (Palmer & Braswell 1995, Wilson 1995, Eckert 1992; Martof et al. 198). As a result, model was including brackish waters that would not be approriate habitat. I altered this species' model as a hand model to include only nesting beaches and marine waters. MJR 3 January 28. Hydrography Mask: Brackish/Saltwater Only Utilizes flowing water features with buffers of 12m from and unlimited into selected water features. Utilizes open water features with buffers of 12m from and unlimited into selected water features.
